500ml PFA Two-necked Flask

Teflon flasks usually have a round-bellied and narrow-necked appearance, which is significantly different from a beaker. Its narrow mouth is used to prevent the solution from splashing or to reduce the evaporation of the solution, and can be used with rubber stoppers to connect other PTFE equipment.

Product Description

PFA flasks usually have a round belly and narrow neck. Its narrow mouth is used to prevent the solution from splashing or reduce the evaporation of the solution, and can be used with rubber stoppers to connect other utensils, rotary evaporators, condensers, Separating funnel, delivery tube, etc. When the solution is corrosive (such as hydrofluoric acid) and requires a long reaction or heating to reflux, the PFA flask is selected as the container.


The main purpose

(1) Reactor between liquid and solid or liquid;

(2) Assembling a gas reaction generator (normal temperature, heating);

(3) Distillation or fractionation of liquids (flasks with branch pipes are also called distillation flasks).


Product advantages:

1. PFA flasks have single-neck, two-neck, three-neck and four-neck, 17, 19 and 24 standard mouth designs, and each standard mouth is equipped with a stopper.

2. The single neck is integrally formed, and the two, three or four necks are welded

3. Use high-purity PFA material, translucent and visible, low background, no dissolution, no precipitation, pure and pollution-free

4. Temperature resistance -200 to 260°C

5. Strong corrosion resistance (various strong acids and alkalis and organic solvents)

6. PTFE round bottom flasks can be processed according to your requirements, and the specifications and sizes can be processed

7. Rich production experience, exquisite processing, smooth inner wall without water, and uniform wall thickness


Package product:

1. Polytetrafluoroethylene condenser tube: used to condense the gas to be collected after the sample reaction into liquid

2. Thermometer: used to measure the specific experimental temperature in the reaction tank during the experiment (the glass tube can be put into the reactor with a Teflon tube)

3. Polytetrafluoroethylene constant pressure separatory funnel: used to control quantitative sample addition

4. Teflon collection bottle: used for the collection and storage of reactants after condensation.

5. PTFE stirring paddle: stir the sample and fully react
